SPECIFICATION forming part of Letters Patent No. 387,972, dated August 14, 1888.

Application filed March 30,1358. Serial No. 268,988. (No model.)

To @ZZ whom, t may concern:

Be it known that I, WILLIAM B. FoLsoM, a citizen of the United States, residing at Salt Lake City, in the county ofSalt Laheand TerritoryofUt-ah, have invented certain new and useful Improvements in Thill-Oouplings; andIdo hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which forni apart of this specification.

Myinvention has reference to thill-couplings for vehicles; and it consists in the improved construction hereinafter described and explained, whereby the generalstrneture of this class of devices is improved and rattling or loosening of the parts prevented.

In the accompanying drawings, forming a part of this specification, Figure l is a perspective view of niy improved coupling. Fig. 2 is a section of the sanie on the dotted line xx, Fig. l. Fig. Sisapcrspective View of a inodt lication, and Fig. et a detailed view of the central hearing bolt or pin of the saine.

A represents a portion of thethill-clip, having the usual parallel perforated ears, B, hetween which rests the loop G of the shaft, the said loop heilig perforated, as ordinarily, to register with the perforations in the clip-ears.

D represents the hearing holt or pin, which hears in the ears B of the clip and projects therefrom at either end, as shown most clearly in Fig. 2. The said holt or pin D consists of two portions or sections, c b, each of which is tapered at its outer portion, while their inner ends are depressed to conjointly and centrally present a strict cylindrical bearing for the shaftloop, the said depressed portion forming shoulders c, which afford lateral bearings for the sliaft-loop- The two sections a b of the pin are securely held relative to each other by means of a threaded sl'1ank,d,of the portion c, adapted to enter and engage a threaded opening therefor iu the section b, the relative sizes of the said shank and opening heilig such as to permit the said shank to he screwed sufficiently far enough into the said opening` to permit the depressed portions to closely approach each 5o other, as indicated in Fig. 2, thereby presenting at their center practically an unbroken cylindrical hearing.

The major portion ofthe conical ends ofthe bearing bolt or piu D projects beyond the ears, 55 as before mentioned, and each is adapted to receive a sleeve, E, which is provided with a central conical perforation of a size sufficient to enable the said sleeve to be snugly and neatly slipped upon the said conical end, the 6o major portion of the external face, e, of said sleeve being threaded to adapt the said sleeve to engage and enter the internal threaded face,

f, of the adjacent ear B. As illustrated in Fig.

2, the said sleeve enters said ear sulciently 65 far to leave exposed beyond said ear a portion of its threaded face, which exposed portion is adapted for the engagement and retention of a lock-nut, g, the latter being capable of being screwed on the threaded portion until it comes 7o in contact with the side of the ear and hears rigidly and firmly thereagainst.

Freni the foregoing it will he obvious that the construction of the bearing pin or bolt is such that its sections are connected to each 7 5 other at the center of said bolt, which connection is concealed by the shaft-loop; that the connection is such as to forni a continuous bearing for said shaftloop without bringing any of the strain directly upon the threaded shank 8o c of the section @,and, further, that the location and adjustment of the sleeves E is such that the said sleeves hold said bearing pin or bolt rigid relative to the ears D, and thereby overcome any tendency ofthe sections a b to lat 85 eral separation.

In the modified construction illustrated in Figs. 3 and 4 the bearingpin D is represented as consisting of two conical sections, a b, the section ce being provided with an elongated go shank, c, the portion of whiehininiediately adjacent to the inner end of the conical sections a being left nnthreaded, while the threaded portion c is designed to traverse a threaded opening in the section 7i, which threaded openg5 ing extends entirely through the saine.

It will he obvious from the last-described construction that the inner portions of the sections a b present the lateral bearing-shoulders for the shaft-loop, While the unthreaded exposed portion of the shank c affords a central bearing for said loop.

I do not limit myselfto the precise construction or design of the device herein specified, as either said construction or design may be modified Without departing from the spirit of my invention. The location and operation of the nutsg` a'l'ord a good opportunity for enhancing the general style and beauty of the device, inasmuch as the said nuts vmay be formed in the shape of an acorn or other neat design.

I claiml. The combination, in a thill coupling, of a clip having ears provided with internallythreaded perforations and adapted to receive 'between them the shaft-loop, a bearing pin or bolt, consisting of two portions adapted to engage each other, and sleeves embracing the ends of said bolt or pin and engaging the threads in the said ears, substantially as set forth.

2. The combination, in a thin-coupling, of a clip provided with parallel ears having perforations internally threaded and adapted to receive between them the shaft-loop, a bearing pin or bolt having a central depressed portion and bearing-shoulder c, and sleeves embracing the ends of said pin or bolt and engaging the threads of the said ears, substantially as set forth.

3. The combination, in athill coupling, of a clip provided with parallel ears having perforations internally threaded, a bearing pin or bolt, sleeves embracing the ends of said bolt and engaging the threads in the said ears, and nuts embracing said sleeves to bear against said ears, substantially as set forth.

In testimony whereof I afix my signature in presence of two Witnesses.

WILLIAM B. FOLSOM.
